Definitions

  • ROLL FEED MICRO-ADJUSTMENT INDICATOR Inventors: Kurt A. Burtch, Middleville; James A. Lewis, Hastings, both of Mich.
  • ABSTRACT A device is provided to assist in more accurately adjusting material roll feeds used in conjunction with industrial presses.
  • a digital indicator which facilitates visual observation of roll feed adjustments in increments of one thousandth of an inch or the like.
  • the invention comprises the means hereinafter fully described and particularly pointed out in the claims, the annexed drawings and the following description setting forth in detail certain structure embodying the invention, such structure being merely illustrative of various forms in which the principal of the invention may be practiced.
  • FIG. 1 is an elevational view of an air driven roll feed micro-adjustment mechanism used in association with an industrial press and in combination with a preferred embodiment of the invention.
  • FIG. 2 is a fragmentary elevational view of a preferred embodiment of the invention.
  • FIG. 3 is a plan view of the embodiment of the invention shown in FIG. 2 and FIG. 4 is a side elevation of the embodiment of the invention shown in FIG. 2.
  • a press crank shaft has an eccentric 12 secured to one end.
  • a connecting rod 14 is pivotally secured in its upper end 16 to eccentric l2, and pivotally secured at its lower end 18 to a lug 20 projecting from a rocker member 22.
  • the rocker member 22 is pivotally mounted on pin 24 secured to the frame 26 of the press.
  • An air motor 28 is drivingly connected to an adjusting screw 30 by means of spur gears 32 and 34-.
  • the adjusting screw 30 in turn is threadedly fastened to adjusting block 36 mounted to slide in ways 38 of rocker member 22.
  • a stub shaft 40 is integral with and extends from adjusting block 36 to pivotally carry the upper end 42 of a rack 44.
  • the lower end 46 of rack 44 makes engagement with a pinion 48 adapted to drive roll 50 of a set of feed rolls 5052.
  • a digital read-out mechanism is indicated in phantom at 54, and is evenly positioned on the axis of pin 24 to minimize the movement of the digital read-out face during operation of the roll feed.
  • press crank shaft 10 rotates to reciprocate connecting rod 14, which reciprocates rocker member 22 about mounting pin 24.
  • Rack 44 is, in turn, vertically reciprocated to rotate pinion 48 and thus drive roll 50 to index stock between feed rolls 50 and 52.
  • an air motor 28 is activated to rotate adjusting screw 30, which, by so rotating, shifts adjusting block 36 either to the right or to the left responsive to the direction of drive of the air motor 28.
  • the stroke of rack 44 will be either shortened or lengthened to rotate drive roll 50 through a greater or lesser angle of rotation.
  • digital indicator 54 is provided with a digital read-out dial face 55 having visual digital indicators 56 which can be set up to represent any increment of measure, and, in the preferred embodiment, will read in terms of thousandths of an inch.
  • the read-out dial can be calibrated to read in millemeters, or any other selected unit of measure.
  • a digital indicator indexing stub shaft 57 extends from the back panel of the indicator housing.
  • the housing 54 is mounted in a bracket 58, which in turn is secured to therocker member 22 for reciprocal movement with the rocker member about the axis of the mounting pin 24.
  • a stub shaft 60 is mounted in the bracket 58, adjacent and normal to the indexing shaft 57.
  • a pair of bevel gears 62 and 64 are mounted on the ends of the shafts 57 and respectively for driving engagment therebetween.
  • a spur gear pinion 66 is mounted on the opposite end of stub shaft 60, for driven engagement with spur gear 68 mounted on adjusting screw 30.
  • the drive means between the adjusting screw 30 and the indexing shaft 57 is designed to index the digital read-out indicator dial 56 one unit for every thousandth of an inch of change in feed length of the material being fed.
  • the operator may watch the read-out dial 56 and, by suitably activating and deactivating the air motor 28, may very closely control the length of material being fed by rolls 50 and 52. Since the digital indicator 54 is mounted where it is subject to the least possible reciprocating motion, the roll feed can be adjusted during actual working of the press, and the operator can observe the amount of adjustment which he is making with facility and with great precision.
  • the pair of bevel gears 62 and 64 have a one to one gear ratio
  • the spur gear pinion 66 and spur gear 68 have a 0.850 to 7.00 gear ratio.
  • adjusting screw 30 may be connected to the stub shaft 60 by chain and sprocket means to provide a desired ratio of turning between the adjusting screw 30 and the indexing shaft 62.
  • a digital indicator mounted on the pivotal axis of said rocker member having visually observable dials; means to index said dials, and drive means between said adjusting screw and said digital indicator indexing means to produce a linear read-out on said digital indicator dials equal to the length of material being fed by the roll feed.
  • said means to index said digital indicator dials comprises a digital indicator indexing shaft, and means drivingly connecting said adjusting screw to said indexing shaft, said means being adapted to provide said digital read-out on said digital indicator dials equal to the length of material being fed by the roll feed.
  • said means comprises a stub shaft mounted adjacent and normal to said indexing shaft; a first frusto-conical rolling drive element on said indexing shaft; a second frusto-conical rolling drive element on one end of said stub shaft in rolling engagement with said first frusto-conical rolling drive element; a first cylindrical rolling drive element on the other end of said stub shaft; and a second cylindrical rolling drive element on the end of said adjusting screw in rolling engagement with said first cylindrical rolling drive element.
  • said means to index the dial of said digital indicator to provide a digital read-out comprises a digital indicator indexing shaft; and gear means drivingly connecting said adjusting screw to said indexing shaft; said gear means being adapted to provide a gear reduction whereby the linear shift of said adjusting block will provide a movement of the material being fed by the roll feed equivalent to the read-out on said digital indicator dial.
  • said gear means comprises a first bevel gear secured to said indexing shaft; a stub shaft rotatably mounted normal to said indexing shaft; a second bevel gear mounted on one end of said stub shaft in driving engagement with said first bevel gear; a first spur gear mounted on the other end of said stub shaft; and a second spur gear mounted on said adjusting screw in driving engagement with said first spur gear.
  • first and second bevel gears have a gear ratio of 1:1; said first spur gear has a gear ratio with said second spur gear of 17:140; and said first spur gear has a pitch diameter ratio with said second spur gear of 0.850:7.000.
  • first and second bevel gears have a gear ratio of l:1; said first spur gear has 17 teeth and a pitch diameter of 0.850 inches; and said second spur gear has teeth and a pitch diameter of 7.000 inches.
